Table 6-2 Setting Commands
Command Description
k
fr
This setting command #00k frq* sets the frequency( frq ) to which refer the correction
factor.
The figure
fr is the ASCII string representing the integer frequency multiplied by 100
giving thus the resolution of 10kHz.
Once the EP-600 has received and granted this command, all measurements will be
corrected using the factor stored in factory related to this frequency.
Sending a frequency which is out of EP-600 range disables frequency correction factor
function.
The reply is an array made of 5 bytes in which the first is the character ‘k’ followed by 4
bytes expressing a 32bit IEEE floating point number(
ff ) in Little Endian notation.
The figure (ff) represents the frequency used by the EP-600
Example of command
#00k 10000* : (Set the internal frequency to 100MHz)
f
n
This setting command #00fn* sets the processing filter ( n ) used for measurements.
The index n must be between 0 and 7.
For further information on filters please refer to separated document
Example of command
#00f2*
e
n
This setting command #00e n* sets the time before the EP-600 auto-switches off after
receiving a recognized command.
Note that this setting is
not permanent and it will be kept only while the EP-600 is ON.
Every time the EP-600 is turned off, the default 180 second is taken.
The argument
n is expressed in second e should be lower than 10800 (3 hours).
The replay to this command is ‘e’ if it has been granted and ‘x’ if the argument is out of
range (in which case the default 180 is taken).
Example of command
#00e 600* : (sets the switch off time to 10 minutes)
!
This setting command #00!* switches the probe OFF. Once it is OFF there is no way to
turn it ON via remote command
Example of command #00!*
